The UHD51A’s Sharpness settings goes from 1 to 15 I believe and I can personally confirm (with comparisons between the UHD51A and UHD60) that UltraDetail can go to 1 but cannot be turned off or totally defeated on the UHD51A unlike the UHD60.
I do believe UltraDetail, like BrilliantColor and other DLP specific features have their time and place when implemented well. I believe some prefer these settings maxed out and that’s fine. For me, on the UHD51A, I wish I could turn UltraDetail off completely if not for all of the time – at least most of the time for me and my various content. BrilliantColor on the other hand I leave at default on the UHD51A because it is implemented well whereas on the UHD60 and its color wheel it is not. On the UHD60, I had to end up turning BrilliantColor down to its lowest setting.
UltraDetail processes the image far more than a "true" 'separate' Sharpness would (at least from what I’ve observed using both the UHD51A and UHD60). I personally prefer UltraDetail off. I do admit that I see the extra sharpness punch it can give the image at times though.
That's interesting, I thought there was a separate setting for the UHD51A since it's missing from the advertisments for the UHD350X. The range was also 1-15 for the UHD350X. Anything above 6 looked unbearable at 1080p.

At least for my taste. These are extreme examples that bring out the visual issues I can have with UltraDetail. Other affected areas of the image are far less noticeable to the eye.
I’ve asked in previous threads regarding firmware, bug fixes, feature requests, etc. that Sharpness on the UHD51A be given a ‘0’ setting that turns UltraDetail complete off. Just the option to turn it off for those of us that don’t want to use it and still allow those that do their full range of settings from 1 to 15. Leave the default at 14 (I believe that’s what it is for most incoming image types).
I would love to leave it at the default setting, unfortunately at 1080p it looks horrible for some reason.
The picture with the default settings is jaw-dropping beautiful at 2160p (with and without HDR), especially when considering the price range of these projectors.
At 1080p things look considerably worse than on my previous W1070+ though, which is not what I expected from this to be honest.
Still, I returned the projector to Amazon now and I consider this a defective unit. If it's really defective or Optoma messed up the default settings, no idea.
No matter how much I messed with the image settings I only got it to look decent, with varying quality depending on the scene shown.

I suspect the issue is with your choice of settings, rather than any defect within your projector. Or maybe the differences between uhd51a and UHD350X are the issue. I can only tell you the results I get from a uhd51a. Good luck!
No idea to be honest, the output by both Windows and LibreELEC is whatever they choose by default, so I would still put the blame on the projector for not handling the input correctly.
Either way, I returned the unit now and will keep my eyes out for a UHD51 or wait until the new BenQ model arrives.
Still, thanks for the information. It really helped me with testing.
One final question: Does the UHD51 also not have any video mute/blanking option? That's something that I really missed from my previous projector while I was testing the UHD350X.
In case anyone is still interested, these are the default values for the Cinema profile on the UHD350X:
